OVM, OVXL, OHV VERTICAL SPEED<br />

CONTROL<br />

This remote speed control may have governed idle, a<br />

choke override, and the option of an ignition remote<br />

stop terminal block.<br />

The speed control is adjusted to the equipment throttle<br />

control by aligning the slot in the speed control lever<br />

with the alignment hole on the mounting bracket.<br />

Place a pin through the two holes, place the equipment<br />

throttle control to the wide open position, hook the<br />

bowden cable end in the control as shown, and tighten<br />

the cable housing clamp. In this position, the gap of<br />

.040" - .070" (1.02 - 1.778 mm) should exist at the<br />

gap location as illustrated. This will assure that the<br />

carburetor will go into full choke when the control is<br />

placed in the start position.<br />

The idle speed is adjusted by turning the idle speed<br />

screw clockwise to increase engine R.P.M. and<br />

counterclockwise to decrease R.P.M. Use tool part #<br />

670326 to adjust the high speed engine R.P.M. Place<br />

the slotted end of the tool onto the adjustment tab<br />

and bend the tab to the left (away from the control) to<br />

increase engine R.P.M.<br />

Throttle plate alignment on all models with speed<br />

controls mounted on intake manifold. This adjusts<br />

choke in control as well (diag. 12 on page 25).<br />

CONTROL<br />

This speed control is adjusted to the equipment throttle<br />

control by aligning the slot in the speed control lever<br />

with the alignment hole on the mounting bracket.<br />

Place a pin through the two holes, place the equipment<br />

throttle control to the wide open position, hook the<br />

bowden cable end in the control as shown, and tighten<br />

the cable housing clamp. In this position, the gap of<br />

.040" - .070" (1.02 - 1.778 mm) should exist at the<br />

gap location as illustrated. This will assure that the<br />

carburetor will go into full choke when the control is<br />

placed in the start position.<br />

NOTE: Assure that the throttle cable has full travel<br />

from wide open throttle to full choke. Hard starting<br />

could result if the cable is not properly adjusted to<br />

allow for full choke.<br />

The idle speed is adjusted by turning the idle speed<br />

screw clockwise to increase engine R.P.M. and<br />

counterclockwise to decrease R.P.M. Use tool part<br />

# 670326 to adjust the high speed engine R.P.M. Place<br />

the slotted end of the tool onto the adjustment tab<br />

and bend the tab to the left (toward the spark plug<br />

end) to increase engine R.P.M.<br />

OHV 11 -17 engines use nylon bushings on the throttle<br />

and choke linkage hook-up points to extend the life<br />

of the linkage and to enhance the stability of the<br />

governor system. Make sure they are in good<br />

condition and in place (diag. 27).<br />
